Owners of their yard often face the problem of pumping contaminated water. Regular pumps can’t do the job. Solid fractions will become clogged in the impeller, or even it may jam altogether. Drainage pumps are used to pump contaminated liquid. Many models even have a solids grinding mechanism. Among summer residents, the karcher dirty water drainage pump is very popular, although there are also many units from other manufacturers.
The difference between drainage pumps at the installation site
All drainage pumps are divided into two types, depending on where they are installed: above water or immersed in liquid.
Land based units
Surface-type pumps are installed near a well or any other drive. Only the hose connected to the unit inlet is immersed in dirty water. In order for the liquid to be pumped out automatically without human intervention, the pump is equipped with a float and automation. The principle of operation of such a scheme is simple. The float is connected to the contacts through which electricity is supplied to the pump motor. When the water level in the tank is low, the contacts are open and the unit does not work. As the liquid level rises, the float rises. At this time, the contacts close, electricity is supplied to the engine, and the pump starts pumping.
Surface pumps are convenient because of their portability. The unit is easy to transfer from one well to another. All main working units are on the surface, which facilitates free access for maintenance. Surface mounted pumping equipment is usually produced with medium power. The units can be used in pumping stations for pumping clean water from a well or well.
Submersible units
The name of the pump already indicates that it is designed to be immersed in liquid. This type of unit does not have a suction port. Dirty water enters through the holes located on the bottom of the pump. The steel mesh filter protects the working mechanism from the penetration of large solid fractions. There are models of submersible pumps equipped with a mechanism that grinds solid fractions. Such a unit can pump out a heavily polluted tank, toilet, artificial reservoir.
The submersible drainage pump works in the same way as the surface unit – automatically. Switching on occurs when the maximum liquid level is reached, and turns off after pumping out. A feature of the submersible pump is reliable electrical insulation and high power of the electric motor.
Criteria for choosing a good pump
User reviews do not always help to choose a submersible drainage pump for dirty water. People can advise good brands and give useful recommendations, and the unit will have to be chosen independently for certain working conditions.
So, when choosing a drainage pump on your own, you need to consider the following nuances:
- When choosing any type of pump for dirty water, it is important to pay attention to what size solids it is designed for. It will depend on this whether the unit will be able to pump out dirty water from an artificial reservoir or it will only be enough to pump out a muddy liquid with impurities of small grains of sand.
- For a submersible pump, an important characteristic is the maximum depth at which it can operate.
- When choosing a unit for pumping hot liquid, you need to find out what temperature mode it is designed for.
- Additionally, it does not hurt to pay attention to the maximum pressure of the pumped liquid, the dimensions of the pump, as well as the material of its manufacture.
When choosing a good pump for pumping dirty water, experts advise paying less attention to the cost and manufacturer. Let it be a domestic or imported unit, the main thing is that it is designed for the specifics of use and copes with the task.

Rating of popular submersible pumps
Based on consumer feedback, we have compiled a rating of submersible equipment for dirty water. Let’s find out which units are in demand now.
Pedrollo
The submersible drainage pump called “Vortex” is equipped with a mechanism for crushing solids. The body is made of durable technopolymer. The power of the unit is enough to pump out dirty water from a well with impurities of particles up to 2 cm in diameter. In 1 hour, the unit passes through itself up to 10,8 m3 dirty liquid. The maximum immersion depth is 3 m. This model of Italian manufacturers is considered the best choice for home use.
See PF 1010
The technique of Japanese manufacturers has always occupied a leading position. A 1,1 kW pump can easily pump out dirty liquid with solid impurities up to 3,5 cm in diameter. The body of the unit is made of impact-resistant plastic. The submersible model is suitable for pumping contaminated water from a basement, pond or any pit.
Dzhileks
The submersible pump of a domestic manufacturer is reliable and affordable. The powerful unit operates at a depth of up to 8 m, equipped with an overheating system and a float switch. The allowable size of solid fractions in dirty water is 4 cm.
Alko
Alko submersible pumps have a high flow capacity. The most popular is the 11001 model, which is capable of pumping 1 liters of dirty water in 200 minute. A big plus is the silent operation of the electric motor. Durable and lightweight plastic housing made the unit mobile. The pump can be quickly put into operation when the basement is flooded, and if necessary, transferred to another problematic place.
PATRIOT F 400
An ideal submersible model for country use. The small unit F 400 is capable of pumping up to 1 m in 8 hour3 water. It is not demanding on the quality of the liquid, as it copes with solid fractions up to 2 cm in diameter. The maximum immersion depth is 5 m. This is enough to immerse the pump into a well or pond. The unit comes with a float.
Pumping equipment Karcher
I would like to dwell on Karcher pumping equipment in more detail. This brand has long gained popularity in the domestic market. Pumps of any type are distinguished by good power, long service life, economy and compact dimensions.
Karher pumps are divided into three groups according to the specifics of use:
- The high pressure pump is used for washing contaminated objects. The units are easy to use in private areas and summer cottages when washing cars, garden equipment, etc. Compact pumps are made of a durable composite resistant to corrosion.
- Drainage models are used for pumping heavily polluted and clean water, as well as other liquids.
- Pressure units are designed for pumping liquid from tanks. Pumps are successfully used for arranging water supply from a well.
A popular drainage pump is the SDP 7000 model. The compact unit is capable of pumping dirty water with solid impurities up to 2 cm in size. With a maximum immersion of 8 m, it is capable of pumping 1 m in 7 hour3 liquids, while creating a pressure of 6 m. The household model is able to compete with semi-professional counterparts in terms of functionality.
